Review on Elitech DMG-1 AC Manifold Gauge Set 2 Way for R134A, R410A, R22 Refrigerants - Includes Hoses, Coupler Adapters, and Carrying Case by Brian Avila

This is a nice and complete set of gauges. Contains tubing, can punch, valve core removal tool in a nice carry case. Meters store minimum and maximum readings. Automatic shutdown if no pressure changes are detected after some time - this feature can be disabled. The low gauge had a low battery warning that came up right out of the box, which is disappointing. Otherwise a good sentence.
